Once Davis arrived at this space, he didn't use his soul sense to quickly but slowly survey the area. He was somewhat wary of this place as it possessed a heavily repressive atmosphere, especially he could feel this pressure on his soul.

Davis narrowed his eyes in response to the scenery he saw with this soul sense! Although the atmosphere here was oppressive, it didn't affect his soul sense much as he freely yet slowly surveyed the area.

The lake was the most promising and eerie point in this place, so he concentrated his senses on that. It was deep blue in color and opaque. Hence he couldn't see anything but could sense.

A strand of soul sense sank into the lake, and he instantly felt a chill on the back of his mind! He quickly severed the soul sense that sank into the lake!

However, nothing happened at the next moment. He felt that something would happen, so he did not wait and unhesitatingly severed the strand of soul sense that sank in the small lake.

Recognizing that nothing happened, he heaved a sigh. He pushed his new strand of soul sense into the lake again and experienced a deep chill in his mind, but this time, he didn't sever it. He further plunged the strand of soul sense, surveyed the lake, and surveyed the lake's size by sliding over its surface.

The lake was no more than fifty meters in diameter, but the depth remained unknown to him as he was still making his way downwards. The strand of soul sense he sent was incredibly slow at this point. He was not doing it on purpose, but it was slowed down by the lake's effects.

By this time, it became evident that this lake was the culprit that produced the white fog that suppressed one's soul.

Furthermore...

'Yin?' Davis pursed his lips as he finally discovered the attribute of the lake. He initially thought that it was Ice, but contrary to his expectations, it was Yin!

'Yin heavily suppresses the soul... I should've known...' Davis mused as he mocked himself, but he couldn't be blamed because he had even read records of how some types of flames could suppress the soul.

He extended a few more strands of soul sense into the lake from the main strand and sent it out in multiple directions.

As the strands of soul sense were making its way in each direction, time passed.

Ten minutes passed.

At this moment, he had only managed to reach a depth of thirty meters, and he could see that the more he descended, the more it affected the speed of his soul sense.

Davis kept musing what he would find here...

However, his expression abruptly froze as he found one of the vines! Unlike the vines present above, it glowed deep blue as if it were painted by the yin nature of the deep blue lake!

His eyes that froze wondered what it was doing here...

'Could it be that lifeform's true body is below this yin attributed lake?' Davis became cautious, but this discovery didn't stop him from his search.

He was well aware that he would probably have to sacrifice his soul essence to Fallen Heaven to kill this lifeform, but he could also be wrong in any case. With a half-hearted reasoning and determined gaze, Davis continued to investigate.

By this time, Nadia had already cleared an escape route and reported it to Davis. She stood by him, watching his actions in confusion. However, she had no idea what was happening or about to happen!

Unlike Davis, she was ultimately not in the know, and he didn't bother to tell her either.

Another twenty minutes passed, and by this time, Davis had reached the fifty-meter mark in the depth of the lake.

Nadia felt worried as she looked at Davis's expression. She couldn't understand how he would become like this just by holding a vein.

Davis's expression had already visibly contorted as he could no longer take the chillness that invaded his soul anymore!

It was somewhat even painful!

However, he didn't want to give up!...

Taking a deep breath, he invoked Fallen Heaven's white tendrils and used its pure and healing power to encase his entire soul sea. The next moment, the chill disappeared while he felt comfortable, calm, and relaxed.

Davis became pleasantly astonished.

The pure white aura even painted his soul sense as it became lively and powerful. His soul sense became no longer impeded by the yin attribute that caused it to become slow.

He felt that he should've used this from the start, but he noticed that his soul force was being rapidly drained to support such a long-distance soul sense that was two hundred kilometers into the ground.

He didn't dare delay and continued to explore the deep blue lake.

It quickly sank further, but after reaching a few meters deep in mere few seconds, Davis hung his mouth agape as he saw the vision provided by his soul sense!

The surroundings radiated a mysterious azure as if it were seen through a sapphire pearl. The glow radiated, especially strongly at the center, but he could make out the outline of a small candle flame swaying along with the deeply still lake.

"..."

Davis went flabbergasted before his lips twitched. He didn't think his luck, or rather... Natalya's luck would be this impressive!

'A Yin Essence...' Davis's eyelids trembled as he could make out its level!

'A Low-Level Emperor Grade Yin Essence...'

This Spirit Attribute Source is something that is directly a stage above the Derelict Extinction Lightning! And not only was it at a stage higher, but it was also even rarer than the normal Spirit Attribute Sources one could find in the Fifty-Two Territories!

The Yin Essence's presence made him tremble in the level of the soul!

The gap between King Grade and Emperor Grade was something he knew well off because he had to sacrifice his soul essence to make an Eighth Stage Expert his slave when he was at the Peak-Level Mature Soul Stage.

As for the Imperial Protectors, unfortunately, they did not protect their souls with their essence energy. Hence, Davis was easily able to make them his slaves without sacrificing his soul essence.

A heaven-defying being such as Fallen Heaven had to resort to consuming his soul essence to best them. The gap between the stages could be clearly seen from this fact.

Noticing the azure candle flame flicker with beauty and elegance, it took him a while to calm down. He then subsequently noticed the other eight objects that surrounded it. It was none other than those vines! They shone in deep blue and radiated the light as they stretched far!

Davis looked at a particular vine and recognized that it was the one he found. However, these vines were not only surrounding the Yin Essence, but they possessed a huge gaping suction maw pointed at the end. They had their maws open and continuously absorbed the Yin Essence's energy, making the azure yin flame flicker.

Davis's lips twitched.

His soul prowess was usually comparable to that of a High-Level Supreme Soul Stage cultivator even though he was at Mid-Level Supreme Soul Stage! Although it was only a single level, the gap between these two levels wasn't anything small but a big wide chasm.

Normally, the suppression that he would face from a Yin Essence would be heavy, and it remained the case even when it was at a higher stage than him, but he now knew why it failed to affect how soul heavily.

It was because these vines were sucking its energy! They were feeding off the Low-Level Emperor Grade Yin Essence's energy! And judging by how the Yin Essence did not retaliate, he could see that its Will had already been erased!

However, his lips that were twitching slowly curved into a smile.

If it could be said that he was still hesitant to face off with these enormous vines, it could now be said that he was basically raring to kill it so that he could steal this Yin Essence, helping Natalya quickly catch up to them in Essence Gathering Cultivation!

And judging by how this Yin Essence induced both cold and soul suppression, its properties should be these considering that his Derelict Extinction Lightning both had the properties of conjuring illusions and extinction lightning.

He didn't know its title, so its true powers remained a mystery to him.

In any case, this Yin Essence was useless to him, so he didn't feel even a bit of hesitation at the thought of presenting it to Natalya.
